BMW M6 (E24)
Given the thin data state, this read on the BMW M6 (E24) market is low-confidence; however, short-to-medium term forecasts indicate an upward direction with probabilities ranging from 0.53 to 0.57, within a volatile regime. The market shows an overvaluation score of 63.49 and a liquidity score of 40.71, while appreciation momentum is at 56.77. The Dow Jones Industrial index is the strongest leading indicator, correlating at 0.86 with a 6-month lead.
What It's Actually Worth
Blended value of a standard 37 yr, 85k mi example, ~$51.2K now. The green line weighs confirmed auction sales most heavily (the amber dots — what cars actually hammered for), blends in fast-selling "just-missed" listings, and lightly smooths out month-to-month composition noise.
Did our model work? 72% direction calls right
Each faint amber line is a forecast we would have made at that point in the past (12-mo horizon), drawn against what actually happened (blue). Over 64 scored forecasts: 72% got the direction right, median value error ±61%.
Walk-forward: each ghost uses only data available at that date — no hindsight. Data-backed market intelligence, not a guaranteed prediction. Figures are modeled estimates from asking prices, sold comps, and public economic indicators; they can be wrong. Not financial advice.

Crystal Ball — What Leading Indicators Signal
Distinct from the trend forecast above: this blends all 8 leading indicators (each at its own lead time, de-duplicated so correlated ones don't double-count) into one signal. Leading indicators are collectively signaling higher over the next ~12 months (moderate conviction — 49% of weighted drivers agree), driven mainly by Ethereum (USD) and 2-Year Treasury Yield, though Ethereum (USD) points the other way.
Are the indicators agreeing?
Each bar is one driver's current push; longer = more weight. All one side = high conviction; split = low.
